Re: MIDI files problem on a Mac: "Logical end-of-file reached..."

["Chris Roberts" <cpr@musetrap.com>]

MIDI files are completely portable... unless it in a 'mac binary' format,
which is a format which includes a header that defines such things as 
type/creator.
If that were the case, and,it were not converted to a real MIDI file, it
is certanily unknown what would happen. Most MIDI apps look for a signature
(MThd) at the start of the file, and if they don't find it, they refuse
to open it. But, it is possible that they would also scan from the start
looking for the signature and being processing it from there... blah.. 
blah..
blah... But, again, unless there were two versions of this MIDI file (one
for mac, and the other for non-mac), it would make no sense to think that
it was in mac-binary format... well, just my two cents... :)
